Driver/library installation

Drivers

There's no need to install drivers!
Most Linux distributions come with all USB-DUX drivers because
they are part of the mainstream kernel.
For example, the Ubuntu LTS releases Precise Pangolin and Trusty Tahr support all USB-DUX boards.

Libraries

To be able to write software for your USB-DUX you need to install the comedi libraries. Again, these can
be installed with the help of your package manager. There is no need to install from source.
Under UBUNTU or DEBIAN the packages are called:
libcomedi-dev, libcomedi0 and python-comedilib.

Permissions

When you run your program the first time it might not be able to access /dev/comedi0 because you won't have
the permissions to do so. Under UBUNTU there is a group called "iocard" and you need to be a member
of this group to get access to /dev/comedi? as a normal user. If you install the comedi
packages later then you might need to add yourself to this group: sudo usermod -a -G iocard MYUSERNAME.
